History

WESTCAS was formed in 1992 when water and wastewater service providers joined together to share their talents and resources---assuming the name Western Coalition of Arid States or WESTCAS. A grassroots organization, WESTCAS is dedicated to encouraging the development of water programs and regulations which assure adequate supplies of high quality water for those living in the arid regions, while protecting the environment.

WESTCAS has current members in the following states: Arizona, California, Colorado, New Mexico, Nevada, and Texas.
